Spring Repair Kit
SAF-Holland

Designed for fifth wheel spring assemblies, this repair kit targets the primary energy storage and return components that control the lock action. The set is intended to restore proper spring force, tension, and travel in the mechanism, which translates to crisp engagement and reliable release under load. VMRS coding places this item in the 059-001-147 family, signaling its role in the spring portion of the fifth wheel system. The category 42780 identifies it as part of the broader maintenance group for Fifth Wheel components. The kit is designed for field service and shop refurbishment, reducing downtime by supplying a targeted collection of springs, retainers, and related hardware that have wear-prone life cycles. By reestablishing intended spring rates, fleets can maintain consistent jaw closure force, minimize misalignment during coupler actions, and improve operator feedback during hooking and unhooking. There are no cross references listed for this item, so procurement proceeds through standard SAF-Holland channels. As with all safety-critical assemblies, follow torque specs and seating procedures during reassembly and test for secure lock before loading. The category context underscores its role in sustaining performance across varied trailer configurations.
